Zi Wan

Zi Wan, also known as purple aster root, is a traditional Chinese medicine herb that is used to transform phlegm and relieve coughing and wheezing. It is primarily associated with the lung meridian and has a spicy, bitter taste and a slightly warm temperature.

The recommended dosage for Zi Wan is 5-9g. It is typically taken orally, either as a decoction or powder, and is often used in combination with other herbs to enhance its effectiveness.

While Zi Wan is generally considered safe and well-tolerated, it is always important to consult with a qualified healthcare practitioner before using any herb or supplement, particularly if you are pregnant, nursing, or have a pre-existing medical condition. In some cases, the use of Zi Wan may be contraindicated or require special precautions.
